Hmmm.. Seems to work here.  Is your working directory really clean?

    jdl.com 872 % make clean
	     CLEAN (libfdt)
	     CLEAN (tests)
	     CLEAN
    jdl.com 873 % make
	     LEX lex.yy.c
	     BISON dtc-parser.tab.c
	     ---- Expect 2 s/r and 2 r/r. ----
    dtc-parser.y: conflicts: 2 shift/reduce, 2 reduce/reduce
	    CHK version_gen.h
	    UPD version_gen.h
	     CC dtc.o
	     CC flattree.o

    Version: DTC 1.0.0-rc1


I hve also verified that at least one other independent build
using this approach produces a correct version string for them
as well.

Ah, ok.  I understand what you mean now.  That part.
So run it the other way instead.  So perhaps have the
Makefile generate the tag using those versioning parts
instead using some "make tagged_release" target?

I lifted the code from the Kernel's Makefile directly, and tweaked
it slightly for lack of Kconfig aspects.

I don't want to tie the code and build mechanism to git too much.
Specifically, we need to be able to support stand-alone tarball
based builds.  For example, I've spoken to the Debian package
maintainer on this issue, and he likes this approach as well as
he says it will make packaging it much easier.

*sigh*
